Bridging the gap between power quality and signal processing This innovative new text brings together two leading experts, onefrom signal processing and the other from power quality. Combiningtheir fields of expertise, they set forth and investigate varioustypes of power quality disturbances, how measurements of thesedisturbances are processed and interpreted, and, finally, the useand interpretation of power quality standards documents. As a practical aid to readers, the authors make a clear distinctionbetween two types of power quality disturbances: * Variations: disturbances that are continuously present * Events: disturbances that occur occasionally A complete analysis and full set of tools are provided for eachtype of disturbance: * Detailed examination of the origin of the disturbance * Signal processing measurement techniques, including advancedtechniques and those techniques set forth in standardsdocuments * Interpretation and analysis of measurement data * Methods for further processing the features extracted from thesignal processing into site and system indices The depth of coverage is outstanding: the authors present andanalyze material that is not covered in the standards nor found inthe scientific literature. This text is intended for two groups of readers: students andresearchers in power engineering who need to use signal processingtechniques for power system applications, and students andresearchers in signal processing who need to perform power systemdisturbance analyses and diagnostics. It is also highly recommendedfor any engineer or utility professional involved in power qualitymonitoring.

Die Qualitat elektrischen Stroms steht nach wie vor weltweit im Mittelpunkt des Interesses. In Erganzung zu bereits bei Wiley erschienenen Nachschlagewerken wendet sich dieser Band besonders den Phanomenen zu, die die Stromqualitat beeinflussen: EMC (elektromagnetische Kompatibilitat) und Oberschwingungen. Vorgestellt werden effektive Verfahren zur Identifikation der Quellen von Harmonischen und zur Bewertung des Einflusses, den sie auf die Leistungsfahigkeit des Systems ausuben. (12/99)

The book presents a methodology for detection and quantification disturbances of power quality energy. Digital signal processing (DSP) is applied to simulated and measured disturbances. The use of DSP enables the construction of digital filters for the detection of events, and the estimation of the frequency of voltage and current signals. The proposed algorithm quantified the disturbances in according with standards. The program developed was tested using simulated disturbance for its validation. Field measurements were used to assess the robustness of the algorithm against signal noise and other disturbances. This research presents effective and practical software that can be used to develop a new device for measuring the disturbances of Power Quality Energy. The results obtained through the analysis of data (simulated and measurements) validated the proposed algorithm.

We are immersed in the so-called digital energy network, continuously introducing new technological advances for a better way of life. Numerous emerging words are in the spotlight, namely: Internet of Things (IoT), Big Data, Smart Cities, Smart Grid, Industry 4.0, etc. To achieve this formidable goal, systems should work more efficiently, and this fact inevitably leads to power quality (PQ) assurance. Apart from its economic losses, a bad PQ implies serious risks for machines, and consequently for people. Many researchers are endeavoring to develop new analysis techniques, instruments, measurement methods, and new indices and norms that match and fulfil the requirements regarding the current operation of the electrical network. This book offers a compilation of the some recent advances in this field. The chapters range from computing issues to technological implementations, going through event detection strategies and new indices and measurement methods that contribute significantly to the advancement of PQ analysis. Experiments have been developed within the frames of research units and projects, and deal with real data from industry and public buildings. Human beings have an unavoidable commitment with sustainability, which implies adapting PQ monitoring techniques to our dynamic world, defining a digital and smart concept of quality for electricity.

POWER QUALITY MEASUREMENT AND ANALYSIS USING HIGHER-ORDER STATISTICS Help protect your network with this important reference work on cyber security Power quality (PQ) in electrotechnical systems refers to a set of characteristics related to the movement of energy and the delivery of voltage to consumers in the highest standard. As electricity networks change and adapt to new technologies and concepts of energy within a future Smart Grid, it has become clear that standardized methods by which stability and accuracy of electrical service along a network are currently measured are no longer enough to solve inherent issues in service and ensure established requirements are met. Power Quality Measurement and Analysis using Higher-Order Statistics reflects the latest information related to PQ (Power Quality) analysis solutions, particularly that related to the implementation of new quality indices in the domain of higher-order statistics (HOS). The authors—noted experts on the topic—carefully address the detection of PQ problems from two perspectives: the detection of specific events that occur on networks in isolation and continuous monitoring detection. In doing so, the authors demonstrate the use of HOS in current waveform models, enabling the characterization of different power circuit topologies and loads. This book thereby expertly explores the benefits of using HOS, bridging the gap between signal processing and power, and building a better understanding for readers. Power Quality Measurement and Analysis using Higher-Order Statistics readers will also find: A unique methodology for PQ analysis through its combination of HOS and PQ monitoring A proposal for new measurement solutions that can be easily implemented into modern instrumentation The detection of PQ problems from multiple perspectives The use of HOS in current waveform models, which enables the characterization of different power circuit topologies and loads Pitched at a specialized level, Power Quality Measurement and Analysis is an essential reference for researchers, academics, and industry insiders, as well as advanced students in this field.

Frequency disturbances, transients, grounding, interference...the issues related to power quality are many, and solutions to power quality problems can be complex. However, by combining theory and practice to develop a qualitative analysis of power quality, the issues become relatively straightforward, and one can begin to find solutions to power quality problems confronted in the real world. Power Quality builds the foundation designers, engineers, and technicians need to survive in the current power system environment. It treats power system theory and power quality principles as interdependent entities, and balances these with a wealth of practical examples and data drawn from the author's 30 years of experience in the design, testing, and trouble-shooting of power systems. It compares different power quality measurement instruments and details ways to correctly interpret power quality data. It also presents alternative solutions to power quality problems and compares them for feasibility and economic viability. Power quality problems can have serious consequences, from loss of productivity to loss of life, but they can be easily prevented. You simply need a good understanding of electrical power quality and its impact on the performance of power systems. By changing the domain of power quality from one of theory to one of practice, this book imparts that understanding and will develop your ability to effectively measure, test, and resolve power quality problems.
